Description

この発明は、加湿空気を室内へ供給する加湿装置に関するものである。   The present invention relates to a humidifier that supplies humidified air into a room.

従来、この種のものでは、貯水タンク内の水から加湿空気を発生させ、送風ファンにより器具本体内に取り込んだ空気を貯水タンクを通過させ加湿空気を室内に送風する加湿装置があり、貯水タンクの上部に室外から吸い込んだ空気を流通させる空気流通路が載置され、送風ファンが駆動することで室外から器具本体内へ乾燥空気を吸い込み、空気流通路を介して貯水タンク内へ乾燥空気を流入させ、加湿手段空気発生手段により乾燥空気に水分を含ませて発生した加湿空気を送風口から室内へ送風することで、室内の加湿を可能としていた。(例えば、特許文献1)   Conventionally, in this type, there is a humidifying device that generates humidified air from the water in the water storage tank, passes the air taken into the instrument body by the blower fan through the water storage tank, and blows the humidified air indoors. An air flow passage that circulates the air sucked from the outside is placed on the upper part of the unit, and when the blower fan is driven, the air is sucked from the outside into the instrument body, and the dry air is sucked into the water storage tank through the air flow passage. The humidification air generated by adding moisture to the dry air by the humidifying means air generating means is blown into the room from the air blowing port, so that the room can be humidified. (For example, Patent Document 1)

しかし、この従来のものでは、貯水タンクの上部外縁に形成されたタンク側フランジ面と、空気流通路の下部外縁に形成された流通路側フランジ面との間に間隙が形成され、当該間隙が所定距離の間隔を有していることで、貯水タンク内の圧力よりも貯水タンク外の圧力が高くなり、送風ファンが駆動すると送風経路内の空気が空気流通路の開口と間隙とから貯水タンク内部へ入り込むことで貯水室内で発生した水滴が間隙内に入り込むことが阻止され、タンク側フランジ面と流通路側フランジ面との間にパッキンを設置せずとも水滴が間隙へ侵入するのを防止していたが、各製品毎の固定手段での固定具合の差や部材毎の製品バラツキにより、タンク側フランジ面と流通路側フランジ面の間隙の所定距離が一定に保たれず、貯水タンク内外の圧力差のバランスが崩れて貯水タンク外から内へ入り込む空気量が減ってしまい貯水タンクの水が間隙に侵入し、各フランジ面に水アカやカルキ等の汚れが発生して貯水タンク外への水漏れを誘発することから、改善の余地があった。   However, in this conventional one, a gap is formed between the tank side flange surface formed at the upper outer edge of the water storage tank and the flow passage side flange surface formed at the lower outer edge of the air flow passage, and the gap is predetermined. By having the distance, the pressure outside the water tank becomes higher than the pressure inside the water tank, and when the blower fan is driven, the air inside the air flow path is opened from the opening of the air flow passage and the gap inside the water tank. The water droplets generated in the water storage chamber are prevented from entering the gap, and the water droplets are prevented from entering the gap without installing a packing between the tank side flange surface and the flow passage side flange surface. However, the predetermined distance between the tank side flange surface and the flow passage side flange surface is not kept constant due to the difference in the fixing method of each product and the product variation of each member. The balance of the pressure difference is lost and the amount of air entering from the outside of the water storage tank is reduced, so that the water in the water storage tank enters the gap, and dirt such as water stains and chalk are generated on each flange surface. There was room for improvement because it induced water leakage.

上記課題を解決するために、本発明の請求項1では、器具本体と、当該器具本体内にあり水を貯水する貯水タンクと、当該貯水タンクの上部に載置され空気が流入する開口を備えた空気流通路と、前記貯水タンクの上端外縁に形成されたタンク側フランジ面と、当該タンク側フランジ面に対向し前記空気流通路の下部外縁に形成された流通路側フランジ面と、前記タンク側フランジ面と前記流通路側フランジ面との間で所定距離の間隔を有し前記貯水タンクの内外を貫通するよう形成された間隙と、前記タンク側フランジ面と前記流通路側フランジ面とを固定する固定手段と、前記貯水タンク内の水から加湿空気を発生させる加湿空気発生手段と、前記器具本体に形成された吸気口から吸い込んだ空気を前記空気流通路の開口を介して前記貯水室内を通過させ送風口から加湿空気を送風する送風ファンと、当該送風ファンと前記空気流通路との間に形成され流路の途中に前記空気流通路の開口と前記間隙とが配置された送風経路と、を備え、
前記固定手段で前記タンク側フランジ面と前記流通路側フランジ面とを固定したとき、前記間隙の所定距離を一定に保持する保持手段を前記タンク側フランジ面又は/及び前記流通路側フランジ面に形成したことを特徴としている。
In order to solve the above-mentioned problems, according to claim 1 of the present invention, there is provided a device main body, a water storage tank in the device main body for storing water, and an opening that is placed on the water storage tank and into which air flows. An air flow passage, a tank-side flange surface formed on the outer edge of the upper end of the water storage tank, a flow passage-side flange surface formed on the lower outer edge of the air flow passage so as to face the tank-side flange surface, and the tank side A gap that has a predetermined distance between the flange surface and the flow passage side flange surface and that passes through the inside and outside of the water storage tank, and a fixing that fixes the tank side flange surface and the flow passage side flange surface. Means, humidified air generating means for generating humid air from water in the water storage tank, and air sucked from an air inlet formed in the appliance body through the opening of the air flow passage. A blower fan that passes through the room and blows humidified air from the blower opening, and a blower that is formed between the blower fan and the airflow passage and in which the opening of the airflow passage and the gap are arranged in the middle of the flow path A route, and
When the tank-side flange surface and the flow passage side flange surface are fixed by the fixing means, holding means for holding a predetermined distance of the gap constant is formed on the tank side flange surface and / or the flow passage side flange surface. It is characterized by that.

また、前記保持手段は、前記タンク側フランジ面又は/及び前記流通路側フランジ面に形成され少なくとも前記間隙の所定距離の高さを有した凸部であることを特徴としている。   The holding means is a convex portion formed on the tank side flange surface and / or the flow passage side flange surface and having a height of at least a predetermined distance of the gap.

この発明によれば、固定手段でタンク側フランジ面と流通路側フランジ面とを固定したとき、間隙の所定距離を一定に保持する保持手段をタンク側フランジ面又は/及び流通路側フランジ面に形成したので、貯水タンク内外の圧力差のバランスが崩れることが阻止され、間隙を介して貯水タンク内へ入り込む空気量を一定に保持することができるため、パッキンを設置せずともタンク側フランジ面と流通路側フランジ面との間に水滴が付着することがなく、水アカやカルキによる汚れの発生を防止することができ、貯水タンク外への水漏れの誘発を未然に阻止することが可能となる。   According to this invention, when the tank side flange surface and the flow passage side flange surface are fixed by the fixing means, the holding means for keeping a predetermined distance of the gap constant is formed on the tank side flange surface and / or the flow passage side flange surface. Therefore, the balance of the pressure difference between the inside and outside of the water storage tank is prevented from being lost, and the amount of air entering the water storage tank through the gap can be kept constant. Water droplets do not adhere to the road side flange surface, so that it is possible to prevent the occurrence of dirt due to water stains and calcite, and to prevent the leakage of water outside the water storage tank.

また、保持手段は、タンク側フランジ面又は/及び流通路側フランジ面に形成され少なくとも間隙の所定距離の高さを有した凸部であるので、複雑な形状を用いることなく間隙の所定距離を一定に保持することができる。   Further, since the holding means is a convex portion formed on the tank side flange surface and / or the flow passage side flange surface and having a height of at least a predetermined distance of the gap, the predetermined distance of the gap is constant without using a complicated shape. Can be held in.

ステップS101の洗浄モードが終了したら、制御部32は、貯水温度センサ22で検知される貯水温度が室温と同値になるまで加熱ヒータ制御手段35で加熱ヒータ21をON状態にして、ミストモータ11及び送風ファン14が所定の回転数となるようミストモータ制御手段33及び送風ファン制御手段34で制御する立ち上げ動作を実行する立ち上げモードを行う(ステップS102)。   When the cleaning mode of step S101 is completed, the control unit 32 turns on the heater 21 with the heater control means 35 until the water storage temperature detected by the water storage temperature sensor 22 is equal to the room temperature, and the mist motor 11 and A start-up mode for executing a start-up operation controlled by the mist motor control means 33 and the blower fan control means 34 is performed so that the blower fan 14 has a predetermined rotational speed (step S102).

ステップS102の立ち上げモードが終了したら、制御部32は、図示しない加湿スイッチ及び風量スイッチで設定された加湿レベルと風量レベルとに基づいて、ミストモータ11と送風ファン14とが所定の回転数で駆動するようミストモータ制御手段33と送風ファン制御手段34とで回転数を制御し、加熱ヒータ21のON/OFF状態を加熱ヒータ制御手段35で切り替えて制御して、加湿レベルと風量レベルとに合わせた所定の温度範囲内にするミスト運転を実行する通常運転モードを行う(ステップS103)。   When the start-up mode in step S102 ends, the control unit 32 causes the mist motor 11 and the blower fan 14 to rotate at a predetermined number of rotations based on the humidification level and the airflow level set by a humidification switch and an airflow switch (not shown). The rotational speed is controlled by the mist motor control means 33 and the blower fan control means 34 to drive, and the ON / OFF state of the heater 21 is switched by the heater control means 35 to control the humidification level and the air flow level. A normal operation mode for executing a mist operation within the predetermined temperature range is performed (step S103).

前記通常運転モードが実施されると、送風ファン14により器具本体1の底面に形成された吸気口19から吸い込まれた乾燥空気が器具本体1の上部方向へ送風され、貯水タンク8の上流側に形成された送風経路20内を乾燥空気が流通し、送風経路20の途中に配置された開口16から風洞15へ入り込んだ乾燥空気と、送風経路20の途中に配置された間隙39から入り込んだ乾燥空気とが貯水タンク8内に流入し、加湿空気発生手段により発生したミストを含む加湿空気となって気水分離ケース17内を上昇して、気水分離ケース17内に設置されたバッフル板18により大径水滴が捕集されることで、微細な水滴を含む加湿空気のみが送風口2から室内へ送風される。   When the normal operation mode is performed, the dry air sucked from the air inlet 19 formed on the bottom surface of the instrument main body 1 by the blower fan 14 is blown upward toward the instrument main body 1, and upstream of the water storage tank 8. Dry air circulates in the formed air flow path 20, and the dry air that has entered the wind tunnel 15 from the opening 16 disposed in the middle of the air flow path 20 and the dry air that has entered from the gap 39 disposed in the middle of the air flow path 20. The air flows into the water storage tank 8, becomes humidified air containing mist generated by the humidified air generating means, rises in the steam-water separation case 17, and is installed in the steam-water separation case 17. By collecting the large-diameter water droplets, only humidified air containing fine water droplets is blown into the room from the blower opening 2.

また、制御部32は、前記通常運転モードが開始されたら時間カウントを開始し、カウントした時間が所定の運転時間を経過したと判断したら後述する水入れ替え動作を開始して、所定の水入れ替え時間である10分間が経過したと判断したら、水入れ替え動作を終了させ、ミスト運転を再開する。   Moreover, the control part 32 will start time count, if the said normal operation mode is started, and will start the water replacement operation | movement mentioned later when it judges that the counted time has passed the predetermined | prescribed operation time, and predetermined | prescribed water replacement | exchange time When it is determined that 10 minutes has elapsed, the water replacement operation is terminated and the mist operation is restarted.

ステップS103の通常運転モードが開始されてから経過した時間が16時間となったか、または通常運転モード中に運転スイッチが操作されミスト運転終了の指示があったと判断したら、制御部32は、ミストモータ11を停止させてから排水弁28を開弁して貯水タンク8内の水を排水し、所定時間経過したら給水弁25を開弁して貯水タンク8内を洗浄してから排水弁28を閉弁して貯水タンク8内に所定量だけ貯水する洗浄運転を行い、その後、加熱ヒータ21をON状態にして水を65℃前後に加熱し除菌を行う除菌運転を10分間実施し、10分経過後に貯水タンク8内を冷却する冷却運転を実行し、貯水温度が60℃未満になったら排水弁28を開弁して排水するクリーニングモードを行う(ステップS104)。   If it is determined that the elapsed time from the start of the normal operation mode in step S103 is 16 hours or that the operation switch is operated during the normal operation mode and an instruction to end the mist operation is given, the control unit 32 determines that the mist motor 11 is stopped, the drain valve 28 is opened to drain the water in the water storage tank 8, and when a predetermined time has elapsed, the water supply valve 25 is opened to clean the water tank 8 and then the drain valve 28 is closed. Then, a washing operation for storing a predetermined amount of water in the water storage tank 8 is performed, and then a sterilization operation is performed for 10 minutes with the heater 21 turned on to heat the water to around 65 ° C. and perform sterilization. After the elapse of minutes, a cooling operation for cooling the inside of the water storage tank 8 is executed, and when the water storage temperature becomes less than 60 ° C., a cleaning mode is performed in which the drain valve 28 is opened and drained (step S104).

ステップS104のクリーニングモードが終了したら、制御部32は、乾燥モード(ステップS105)に移行し、送風ファン14が所定の回転数(例えば、800rpm)で駆動するよう送風ファン制御手段34で制御し、所定時間(例えば3時間)だけ送風ファン14を駆動させ続ける乾燥運転を実施して、3時間経過したと判断したら、送風ファン14を停止させて運転を終了する。   When the cleaning mode in step S104 is completed, the control unit 32 shifts to the drying mode (step S105) and controls the blower fan control means 34 so that the blower fan 14 is driven at a predetermined rotational speed (for example, 800 rpm). When the drying operation is continued to drive the blower fan 14 for a predetermined time (for example, 3 hours) and it is determined that three hours have elapsed, the blower fan 14 is stopped and the operation is terminated.

次に、本実施形態における間隙39の所定距離の保持方法について説明する。
まず、前面凸部42によるタンク側フランジ面36と前面フランジ部40との間の間隙39の所定距離の保持方法について図7で説明すると、前面凸部42は、前面フランジ部40の傾斜角度を維持するエンボス加工により、ネジ43を前面凸部42に形成されたネジ穴を介してタンク側フランジ面36に挿着したとき、折り曲げ部38に対して水平方向へ伸びる二点鎖線で示す仮想線分と折り曲げ部38とが交差する位置で成す角度Xが予め試験により決定した数値となる。
これにより、前面凸部42が間隙39の所定距離の高さを有し、かつ前面フランジ部40の各所で間隙39の所定距離のバラツキが生じることがないため、ミスト運転が実施され送風ファン14が駆動したとき、貯水タンク8内の圧力よりも貯水タンク8外の圧力が高い状態が保持され、送風経路20内を流通する空気が間隙39から一定の空気量で常に貯水タンク8内へ入り込むことで、ミスト運転実施時に貯水タンク8内で多量の水滴が発生していても間隙39内へ水滴が入り込まず、タンク側フランジ部36及び前面フランジ部40に水滴が付着しないことから、タンク側フランジ部36と前面フランジ部40との間にパッキンを設置せずとも貯水タンク8外への水漏れを未然に防止することができる。
Next, a method of holding the predetermined distance of the gap 39 in this embodiment will be described.
First, a method for holding a predetermined distance of the gap 39 between the tank side flange surface 36 and the front flange portion 40 by the front convex portion 42 will be described with reference to FIG. 7. The front convex portion 42 determines the inclination angle of the front flange portion 40. An imaginary line indicated by a two-dot chain line extending in the horizontal direction with respect to the bent portion 38 when the screw 43 is inserted into the tank side flange surface 36 through the screw hole formed in the front convex portion 42 by the embossing to be maintained. An angle X formed at a position where the minute portion and the bent portion 38 intersect each other is a numerical value determined in advance by a test.
As a result, the front convex portion 42 has a height of a predetermined distance of the gap 39, and there is no variation of the predetermined distance of the gap 39 in each part of the front flange portion 40. Is driven, the pressure outside the water storage tank 8 is maintained higher than the pressure inside the water storage tank 8, and the air flowing through the air blowing path 20 always enters the water storage tank 8 from the gap 39 with a constant amount of air. Therefore, even if a large amount of water droplets are generated in the water storage tank 8 during the mist operation, water droplets do not enter the gap 39 and no water droplets adhere to the tank side flange portion 36 and the front flange portion 40. Water leakage to the outside of the water storage tank 8 can be prevented without installing a packing between the flange portion 36 and the front flange portion 40.

また、右側面凸部44によるタンク側フランジ面36と右側面フランジ部41との間の間隙39の所定距離の保持方法について図8で説明すると、風洞15が貯水タンク8の上部に載置されネジ43により固定されたとき、略半球形状の右側面凸部44の下端がタンク側フランジ面36と当接することで、折り曲げ部38に対して水平方向へ伸びる二点鎖線で示す仮想線分と折り曲げ部38とが交差する位置で成す角度Yが予め試験により決定した数値となる。
これにより、右側面凸部44が間隙39の所定距離の高さを有し、かつ右側面フランジ部41の各所で間隙39の間隔のバラツキが生じることがないため、ミスト運転が実施され送風ファン14が駆動したとき、貯水タンク8内の圧力よりも貯水タンク8外の圧力が高い状態が保持され、送風経路20内を流通する空気が間隙39から一定の空気量で貯水タンク8内へ入り込むことで、ミスト運転実施時に貯水タンク8内で多量の水滴が発生していても間隙39内へ水滴が入り込まず、タンク側フランジ部36及び右側面フランジ部41に水滴が付着しないことから、タンク側フランジ部36と右側面フランジ部41との間にパッキンを設置せずとも貯水タンク8外への水漏れを未然に防止することができる。
A method for holding the gap 39 between the tank side flange surface 36 and the right side flange portion 41 by the right side convex portion 44 will be described with reference to FIG. 8. The wind tunnel 15 is placed on the upper portion of the water storage tank 8. When fixed by the screw 43, the lower end of the substantially hemispherical right-side convex portion 44 comes into contact with the tank-side flange surface 36, whereby an imaginary line segment indicated by a two-dot chain line extending horizontally with respect to the bent portion 38; An angle Y formed at a position where the bent portion 38 intersects is a numerical value determined in advance by a test.
As a result, the right side convex portion 44 has a height of a predetermined distance of the gap 39, and there is no variation in the gap 39 at each position of the right side flange portion 41. When 14 is driven, a state in which the pressure outside the water storage tank 8 is higher than the pressure inside the water storage tank 8 is maintained, and air flowing through the air blowing path 20 enters the water storage tank 8 from the gap 39 with a constant amount of air. Thus, even when a large amount of water droplets are generated in the water storage tank 8 when the mist operation is performed, the water droplets do not enter the gap 39 and the water droplets do not adhere to the tank side flange portion 36 and the right side flange portion 41. Even if no packing is provided between the side flange portion 36 and the right side flange portion 41, water leakage to the outside of the water storage tank 8 can be prevented in advance.

以上のように、前面フランジ部40のネジ43が挿着されるネジ穴の周辺にエンボス加工した前面凸部42を形成し、また、右側面フランジ部41に略半球形状の右側面凸部44を形成したことで、風洞15を貯水タンク8の上部に載置しネジ43でタンク側フランジ面36と流通路側フランジ面37とを固定したとき、タンク側フランジ面36と流通路側フランジ面37との間の間隙39の所定距離が保持されることで、ミスト運転時に送風ファン14が駆動すると貯水タンク8内の圧力より貯水タンク8外の圧力が大きい状態が保持され、貯水タンク8内外の圧力差のバランスが崩れることがないため、送風経路20から間隙39を介して空気が貯水タンク8内へ流入し、貯水タンク8内で水滴が飛散してもタンク側フランジ面36及び流通路側フランジ面37に水滴が付着せず、水アカやカルキ溜まりによる水漏れの発生を未然に防止することができる。   As described above, the front convex part 42 embossed is formed around the screw hole into which the screw 43 of the front flange part 40 is inserted, and the right side convex part 44 having a substantially hemispherical shape is formed on the right side flange part 41. When the wind tunnel 15 is placed on the upper part of the water storage tank 8 and the tank side flange surface 36 and the flow passage side flange surface 37 are fixed with the screws 43, the tank side flange surface 36 and the flow passage side flange surface 37 are When the air blowing fan 14 is driven during the mist operation, a state in which the pressure outside the water storage tank 8 is larger than the pressure inside the water storage tank 8 is maintained, and the pressure inside and outside the water storage tank 8 is maintained. Since the balance of the difference is not lost, even if air flows into the water storage tank 8 from the air passage 20 through the gap 39 and water droplets scatter in the water storage tank 8, the tank side flange surface 36 and Without adhering water droplets aisle flange surface 37, the occurrence of water leakage due to reservoir water red and chlorine can be prevented.

なお、本実施形態では流通路側フランジ面37を構成する前面フランジ部40に前面凸部40、右側面フランジ部41に右側面凸部44を形成した内容で説明したが、間隙39が所定距離を保持できればよいことから、タンク側フランジ面36に前面凸部40、右側面凸部44を形成し、間隙39の所定距離を保持したものであってもよい。   In the present embodiment, the front flange portion 40 constituting the flow passage side flange surface 37 has been described as having the front convex portion 40 and the right side flange portion 41 having the right side convex portion 44. However, the gap 39 has a predetermined distance. As long as it can be held, the front side convex portion 40 and the right side convex portion 44 may be formed on the tank side flange surface 36 to hold a predetermined distance of the gap 39.

また、本実施形態では風洞15の下端にある流通路側フランジ面37について説明したが、気水分離ケース17の下端についてもタンク側フランジ面36と当接する箇所について前面凸部40、右側面凸部44を形成することで、気水分離ケース17の下端と貯水タンク8の上端との間にある間隙39の貯水タンク8内へ空気量が乱れることなく流入するので、タンク側フランジ面36と流通路側フランジ面37とに水滴が付着せず、水アカやカルキ溜まりによる水漏れの発生を未然に防止することができる。   Further, in the present embodiment, the flow path side flange surface 37 at the lower end of the wind tunnel 15 has been described. By forming 44, the air amount flows into the water storage tank 8 in the gap 39 between the lower end of the air / water separation case 17 and the upper end of the water storage tank 8 without being disturbed. Water droplets do not adhere to the road side flange surface 37, and it is possible to prevent the occurrence of water leakage due to water scum and chalk accumulation.
